PARIS- Serena and Venus Williams edged closer to a third round sister showdown at the French Open.
Women's top seed Serena Williams, who won the 2013 title to add to her 2002 maiden triumph in the French capital, started her 13th Roland Garros with a 6-2 6-1 win over French wildcard Alize Lim.
Three days after the close friends were snapping 'selfies' of themselves at the players' party at the Eiffel Tower, Williams fired 37 winners past Lim, the world 138, although a sloppy final game left her relying on a fifth match point to seal victory.
The win extended Williams' record in opening rounds of the majors to 54-1 - her only blip being a first round exit to Virginie Razzano in Paris three years ago.
Williams will face either compatriot Grace Min or Spain's Gabrine Muguruza for a place in the third round where she could then play big sister Venus.
Venus, the 29th seed and 2002 runner-up, began her campaign with a 6-4 6-1 win against Swiss 17-year-old Belinda Bencic who was two and a half years from being born when the American made her professional debut back in 1994.
